We are morphing as we go through things, and then we're presented with the notion of a soul. A soul implies more than just the preservation of energy. Science will tell you that you can explode a person, but their energy still exists - even if they're decimated, the universe will preserve that in the form of heat or whatever it is. So there's a preservation of our molecules or whatever, but is there a preservation of a thing that's called the self if that thing is not actually ever one thing?
